Trader consensus on Polymarket centers on a 16°C high in Shanghai on March 25 at 32% implied probability, with 17°C (28.5%) and 15°C (20.5%) close behind, driven by converging ECMWF and GFS model runs forecasting 15-17°C amid persistent mild southerly flows and partial cloud cover. Late March climatology shows average highs of 14-15°C at Xujiahui station, but recent advection of warmer air masses from the south has nudged projections upward, differentiating these outcomes from cooler tails like 13°C. Uncertainty lingers from potential shortwave troughs, with final NWP updates and official observations determining resolution.
